Filed July 25, 1957, Ser. No. 674,082 2 Claims. (Cl. 204-38) Our invention relates to a storm window and a storm door which has sliding screens and glass sections as parts thereof. In the usual type window or door as it is manufactured today, there is a triple track within the frame. One track has a screen and the other two tracks each have glass inserts. By moving the various inserts up and down in the frame the window or door may be entirely closed by the two glass panels, or it may have the two glass panels on top and the screen panel on the bottom to permit ventilation, or vice versa, or any combination of screen and glass that can be made by sliding the various components up or down.

The main purpose of providing the combination screen and storm window or door is to insure weatherproofing of a structure during the winter, and protection from insects during the summer. In the ordinary combination window or door there is frequently a condition of draft through the wide channels which hold the window and screen panels.

It is an object of our invention to provide a process for further weatherproofing the channels and various parts of the device and for making an improved combination storm and screen window or door. It is a further object of invention to make such a device by our process which comprises treating the channels, and other portions of the window or door with weather-insulating material.

Prior to our invention, because of the close tolerance involved and the necessity of maintaining the inserts in slideable position in the channels, it was not practicable to provide insulating material in the channels as the addition of any extra material in the channels would interfere with the operation. By the use of our invention we have provided for the introduction of insulating material in the channels and other parts which not only provides insulation from the weather but also aids in the operation of the moving parts of the devices.

Further objects and advantages will appear from the specification hereinbelow.

In the accompanying drawings:

FIG. 1 is an elevation of a combination storm and screen window as seen from the inside of a structure.

FIG. 2 is a cross-section along the lines 2-2 in FIG. 1 showing our insulating material fully installed throughout the entire portion of the channels of the window.

FIG. '3 is a cross-sectional view similar to FIG. 2 with the screen and window inserts removed and showing an alternate form of treating the window by placing the insulating material only on the sides of the channels nearest the inside of the structure.

FIG. 4 is a cross-section of a part of the aluminum extrusion from which our window or door is made.

FIG. 5 is a cross-section of the same extrusion shown in FIG. 4 after having been anodyzed.

FIG. 6 is a cross-section of the same extrusion shown in FIGS. 4 and 5 with the addition of a coating of adhesive over the anodyzed surface.

FIG. 7 is the same cross-section shown in FIGS. 4, 5 and 6, with the addition of the insulating material adboring to the adhesive.

Similar numerals refer to similar parts throughout the several views.

The window 10 is made out of aluminum extrusions in a manner well known to the art. We ordinarily extrude our component parts in lengths up to 20 feet, and then,

manufacture them into a window in the usual manner. The window we prefer to manufacture comprises a frame 11 having three tracks or channels 12. The channels 12 run continuously around the inside of the entire frame 11. In each channel 12 we place either a window insert 13 or a screen insert 14. The inserts 13 and 14 are slightly more than half as high as the heights of the channels 12 in which they are inserted. Thus, when an insert 13 is raised as high as it can go, and another insert 13 is lowered as far as it can go, they will form a complete glass enclosure within the window frame.

In the window 10 which we show in FIG. 1, we have provided two glass inserts 13 and a screen insert 14. By moving the inserts up and down we can provide either a complete glass enclosure or a half screen, half gl-ass enclosure, or an enclosure in which all the elements are either on the top or on the bottom, to provide approximately half of the window 10 with no obstruction, for cleaning and other purposes.

We have thus far described our preferred storm window as it was manufactured prior to our invention. In our present manufacture we use our new process. The first step in our new process is to prepare the extruded aluminum 15. Untreated aluminum 15 will ordinarily not hold paint, enamel or other adhesive. We anodize the aluminum extrusions so that our adhesive will adhere to the components. FIGURE 5 of the drawings shows the aluminum extrusion 15 with the anodized coating 16. Other processes, such as bathing with sulphuric acid will also prepare the metal 15 for the adhesive coating 16.

We then apply an adhesive 17. We prefer to use a resin base adhesive. Synthetic resins as well as enamels and lacquers, all work well as adhesives in our process. The adhesive 17 is applied in a liquid state and before it dries fine shreds of material 18 are applied to the adhesive 17 with a spray gun or other pressure spraying means. The material 18 may be rayon, cotton, wool, nylon or practically any other natural or artificial textile fiber. It may even be made of shredded waste material of these fabrics. The spray pressure is sufficient to shoot the shredded material 18 onto the surface of the adhesive with sufiicient force to make the shreds stand on end against the adhesive. Some of the material 18 will then become fast to the surface of the adhesive, standing on end. The adhesive 17 is then permitted to dry and solidify. This process can sometimes be hastened by applying heat, if desired. There will be a substantial coating of material 18 inside each channel 12, and at such other portions of the window where it is desired to apply same. The combination of the coating of the adhesive 17 and the material 18 serves to ease the inserts 13 and 14 as they are slideably moved up and down in the channels 12 and, more important, serves as a positive weatherproofing material between the moving parts.

Our method of applying the insulating material 18 can be used after the construction of the window or prior to its construction as the pieces of aluminum are extruded. We find that we can extrude the aluminum pieces and apply the insulating material 18 by means of our process in one continuous operation. We can then construct the parts into the window 10 as set forth hereinabove.

Dilferent color tones may be obtained by using dif ferent colored adhesives 17, as well as different colored material 18.

We have described our process and our construction in connection with a window. The same process and construction may be applied to the manufacture of a combination storm and screen door.

While we have described the preferred form of our window and of our process, there may be other constructions and processes of an equivalent nature which will come within our claims, and we desire to be protected for all forms which come within the scope of the claims hereinbelow.

Wherefore, we claim:

1.

2. A method for weatherproofing a metal combination storm and screen window or door' having at least one insert slideably mounted in channels: comprising the steps of first treating the metal of the channels to receive a bonding material by bathing with sulphuric acid, then applying a bonding material to the metal so treated,
